The correct answer is option b, that is, white.
Explanation:
In the presence of the recombinant plasmid within the colonies disruption of lac z gene takes place, which results in no production of the beta-galactosidase enzyme. Due to the non-existence of the beta-galactosidase enzyme, the colonies remain white.
This appearance of blue color in the colonies takes place when the enzyme beta-galactosidase reacts with the substrate X-gal. Thus, in the absence of beta-galactosidase, no reaction occurs and the colonies remain white.
